[GUIDE][XT1033] How to Run GPE ROM With Single SIM Working [KOT49H][Dual Sim Moto G]

Hi Guys, like many of you I have been searching all over the forum on how to get the GPE Rom working on our dual sim variant of the Moto G. Most of us can do away with a single sim and seldom use the second one. After experimenting with the NON-HLOS.bin and fsg.mbn, I found out that the GPE rom doesn't work even if we retain the fsg or modem from the Asia-Retail dual sim roms. So here goes the guide on how to make the GPE rom work with a single sim on the XT1033. You'll need to have adb and fastboot installed or download the minimal adb and extract the contents to the rom folder.


1) Flash complete stock 4.4.2 Retail-GB or (MIRROR- Thanks aqcohen) rom. You'll have a working single sim. (You can use the attached Retail_GB.bat. Copy it over to the extracted folder and run it.)

2) Download and extract The GPE or (GPE MIRROR- Thanks aqcohen) rom.

3) Replace the GPE_XT1032_KOT49H.M004_CFC.bat with GPE_XT1033_KOT49H.M004_CFC.bat (attached) and run it.

4) You should now have the GPE rom with a single sim working.



P.S. This should work with other AOSP based roms like CM which are built for XT1032. Also you can try flashing 'only' the baseband (fsg.mbn) and modem (NON-HLOS.bin) of Retail-GB firmware and see if primary sim works on CM roms.

To flash specific partitions, edit the batch file accordingly.


Press THANKS if worked.

Won't work!

Hey there!
I've already tried and tested flashing Retail.GB modem/radio over AOSP ROMs like CarbonROM, LiquidSmoothROM, and it doesn't work.
ParanoidAndroid does work on XT1033 [Single Sim] by flashing the extra file mentioned in the thread (here) but flashing the same file on other AOSP ROMs dosen't help (the same call not hanging up problem persists).
From what I understand, Doublepranks has ported CM for XT1033 (here) and its the only AOSP ROM which works with single-sim enabled.
I assume it won't be hard to merge AOSP based ROMs with Doublepranks's sources, but I suppose I'll wait until the official CM includes support for XT1033 (as mentioned on CM wiki -- read here).
That is, until a more elegant solution comes along. Fingers crossed! :fingers-crossed:

Edit: By doesn't work, I meant to say partially doesn't work. Internet works just fine, but calling is buggy [can't hang-up the call/Can't receive calls].

Edit: PA is also AOSP. So that makes it 2 AOSP ROM which work with XT1033.

if "You'll have a working single sim." then it's finish step ? sorry to ask

No. By that I meant you'll have the stock Retail-GB rom with single sim functionality.

For AOSP roms try this.

Flash Retail-GB firmware (or only the modem and baseband.)
Flash Custom Recovery.
Flash XT1032 AOSP Based rom like CM.

let me try...
